Next, the operation of group dimming control for simultaneously controlling a plurality of dimming control terminals in the dimming control system will be described with reference to FIG. FIG. 16 shows a case where three dimming switch terminals 2a1-2a3 are controlled by a pattern switch terminal 2c having substantially the same configuration as the group dimming terminal 2b, and each dimming switch terminal 2a is controlled.
The dimming control of the dimming control terminals 3a1 to 3a3 corresponding to 1 to 2a3 is performed. That is, in this example, three dimming switch terminals 2a1 to 2a3 are stored and set as one group in the storage unit 14 of the central control device 1, and the dimming control is collectively performed by the pattern switch terminal 2c.

First, when the pattern switch of the pattern switch terminal 2c is pressed, the storage unit 1 of the central controller 1
4, each of the dimming control terminals 3a1 to 3a3
A "dimming level control command" is transmitted to a3. Then, each of the dimming control terminals 3a1 to 3a3 gradually increases the illuminance of the illumination load L1 by itself in the control unit 33 and the dimming circuit 35. Then, when the illuminance of the lighting load L1 changes to some extent under its own control, an interrupt signal is generated to notify the central control device, and the central control device 1 monitors the illuminance at that time, and controls the dimming switch terminal 2a1. 2a3 is transmitted to each of the dimming switch terminals 2a1-2a3, and the light emitting diodes LD perform level display corresponding to the illuminance of the illumination load L1.

After transmitting the light level information to each dimming control terminal, dimming fade time information and a broadcast control signal for simultaneously starting dimming control are transmitted to perform dimming control. As a result, the dimming level control based on the desired dimming fade time is started simultaneously by the fade time information and the broadcast control signal transmitted after the dimming level information is transmitted.

FIG. 4 is a sequence diagram showing operation steps of controlling the dimming of the light-emitting device 3 and displaying the state of the dimming control on the dimming display terminal 6.

First, when one of the pattern switches S8 of the pattern switch terminal 2c is pressed, the information of the corresponding number is transmitted to the central control unit 1, and the pressed pattern switch S8 is displayed as a display during fade dimming. The corresponding light emitting diode LD2 blinks. The central control device 1 controls each of the dimming control terminals 3a stored in the storage unit 14.
Light control level information and fade time information corresponding to a predetermined pattern number are sequentially transmitted to 1 to 3a3. Next, the broadcast control signal for simultaneously starting the dimming control is
It transmits to the dimming switch terminals 2a1-2a3 and the dimming display terminal 6 corresponding to the dimming control terminals 3a1-3a3.

When the broadcast control signal is received, the light control level is determined based on the light control fade time information of the light control pattern stored in the setting storage unit 65 in order to indicate that the light control is being performed. Of light emitting diodes L corresponding to
D6 is displayed blinking.

When each of the dimming control terminals 3a1 to 3a3 receives the dimming level information for its own address, the terminal enters a change start standby state. From the dimming level to the specified dimming level, the control unit 33 and the dimming circuit 35 start illuminance change so as to gradually increase the illuminance of the illumination load L1 based on the specified fade time. When the fade time has elapsed and the light control level of the received light control level information has been reached, an interrupt signal is generated to notify the central control unit under its own control.

After receiving the interrupt signal, the central control unit 1 receives a return signal corresponding to the control end signal, and controls the dimming switch terminals 2a1-2a3, the pattern switch terminal 2c, and the dimming display terminal. A “light control level display command”, which is a light control end broadcast, is transmitted to 6.

According to the dimming control system described above,
Since the dimming level control based on the desired dimming fade time is started simultaneously by the broadcast control signal, the group fade control operation of the lighting load can be performed even when the number of dimming control terminals 3a is large. Simultaneously, a good dimming scene effect can be realized. In addition, the dimming display terminal 6
Displays the control-in-progress state of the dimming control, so that even when performing the dimming control for a long dimming fade time, it can be easily grasped that the dimming is in progress. In addition, since the control result of the dimming control is displayed on the dimming display terminal 6 based on the dimming level information, the display is performed with a smaller amount of data. Is improved. Also, since the dimming level is displayed by the length of the bar graph, the dimming state can be easily grasped. Further, since the control in-progress state and the level display of the control result are shared, the dimming display terminal 6 can be formed in a small size.

This dimming control system differs from the first embodiment only in the storage contents of a storage means (not shown) in the control section of the dimming control terminal 3a, and the components are the same as those of the first embodiment. This is the same as that of the embodiment.

The light control terminal 3a has storage means for storing light control level data and light control fade time data based on a plurality of identification data. More specifically, the control unit 33 includes a storage unit corresponding to a storage unit (not shown) in the inside, and as shown in FIG. 6A, 64 steps of fade time, dimming level, Are stored as light control patterns corresponding to different identification data.

This dimming control system performs group dimming control for simultaneously controlling a plurality of dimming control terminals.
The central control device 1 replaces the dimming level information and the fade time information in the sequence diagram shown in FIG. 4 with the dimming pattern number corresponding to the identification data and the dimming control terminal 3a1.
3a3 and the dimming display terminal 6.

When each of the dimming control terminals 3a1 to 3a3 receives the identification data corresponding to its own address, it enters a change start standby state. The illuminance change is started so as to gradually increase the illuminance of the illumination load L1 from the level to a predetermined dimming level with a fade time based on the dimming pattern corresponding to the specified identification data. Then, when the fade time elapses and reaches a predetermined dimming level, the dimming control ends.

The dimming display terminal 6 receives the broadcast control signal and displays the dimming fade of the dimming pattern stored in the setting storage section 65 in order to indicate that it is in the dimming control state. The light emitting diodes LD corresponding to the dimming level based on the time information are blinked and displayed. When the fade time has elapsed, the blinking ends.

According to the dimming control system described above,
Since the dimming level control based on the predetermined dimming fade time is performed by transmitting the identification data, the response time of the dimming start to the operation is reduced by reducing the amount of data transmitted from the central controller 1. Is shortened.

[Third Embodiment] FIG. 7 is a sequence diagram showing a control procedure by a central monitoring device of a dimming control system according to a third embodiment.

This dimming control system has the same configuration as that of the first embodiment, except for the content of the control procedure sequence by the central monitoring device. The central controller 1 sends the dimming level information as the dimming control data to each dimming control terminal in the control procedure sequence of the first embodiment, and then sets the dimming fade time information and A broadcast control signal for simultaneously starting the dimming control is transmitted to perform dimming control.

The operation of the dimming control system when performing group dimming control for simultaneously controlling a plurality of dimming control terminals will be described with reference to FIG. FIG. 7 shows three dimming switch terminals 2 by the pattern switch terminal 2c.
a1 to 2a3 to control each dimming switch terminal 2a1 to 2a3.
It is a sequence diagram which shows the operation | movement step which controls the dimming control terminals 3a1-3a3 corresponding to 2a3, and displays the state of dimming control by the dimming display terminal 6.

First, when one of the pattern switches S8 of the pattern switch terminal 2c is pressed, the information of the corresponding number is transmitted to the central controller 1, and the pressed pattern switch S8 is displayed as a display during fade dimming. The corresponding light emitting diode LD2 blinks. The central control device 1 controls each of the dimming control terminals 3a stored in the storage unit 14.
Light control level information corresponding to a predetermined pattern number is sequentially transmitted to 1 to 3a3. Next, fade time information and a broadcast control signal for simultaneously starting dimming control are transmitted to the dimming control terminals 3a1 to 3a3 and the dimming display terminal 6.

The dimming display terminal 6 receives the fade time information and the broadcast control signal, and displays the dimming control state. Of the light emitting diode LD6 is blinked for a period based on the received dimming fade time information. Then, after the elapse of the fade time, the blinking is terminated, and a level display corresponding to the dimming level of the dimming pattern is displayed by lighting a proportion of the light emitting diodes LD6 corresponding to the dimming level.

When each of the dimming control terminals 3a1 to 3a3 receives the dimming level information corresponding to the above address, the dimming control terminals 3a1 to 3a3 enter a change start standby state, and then send fade time information and an instruction by a broadcast control signal. When received, from the current dimming level to the specified dimming level, the illuminance changes so as to gradually increase the illuminance of the illumination load L1 by itself based on the condition of the fade time received by the control unit 33 and the dimming circuit 35. To start. Then, when the fade time elapses and reaches a predetermined dimming level, the dimming control ends.

Each of the dimming switch terminals 2a1-2a
Reference numeral 3 denotes corresponding dimming control terminals 3a1 to 3a3 which are appropriately transmitted from the central control device 1 after the above control is completed.
Is displayed by turning on the light emitting diodes LD corresponding to the dimming level based on the level display command corresponding to the illuminance level of the illumination load L1.

According to the dimming control system described above,
Since the dimming level control based on the desired dimming fade time is started simultaneously with the fade time information and the broadcast control signal transmitted after the dimming level information is sent, the central control device 1 Since the amount of data transmitted from the first embodiment is smaller than that of the first embodiment, the response time to the operation is further shortened. In addition, since the dimming display terminal 6 receives the broadcast control signal and the dimming fade time information and displays a state in which the dimming control is being controlled, the dimming of the dimming control with a long dimming fade time is performed. It can be grasped on the way with a smaller amount of data.

In the above dimming control system, the dimming control terminals 3a1 to 3a3 are stored in a storage unit (not shown) corresponding to the storage means inside the control unit 33, as shown in FIG. )
As shown in FIG. 3, the light control pattern stores 64 levels of dimming levels as dimming patterns corresponding to different identification data as fade time conditions, and the central control unit 1 stores the identification data as the dimming control data. And the dimming fade time information. In this device, the dimming level control based on the desired dimming fade time is started simultaneously with the fade time information and the broadcast control signal transmitted after the identification data is transmitted. The effect of achieving a good dimming scene effect can be achieved with a small amount of data transmission and a small dimming control terminal storage capacity.

[0056]

According to the dimming control system of the present invention, the dimming level control based on the desired dimming fade time is started simultaneously by the broadcast control signal. Even when the number is large, the group fade control operation of the lighting load is performed at the same time, so that a good dimming scene effect can be realized.

Further, the dimming control system according to the second aspect provides, in addition to the effect of the first aspect, dimming level control based on a predetermined dimming fade time by transmitting identification data. Therefore, the response time of the start of dimming to the operation is shortened by reducing the amount of data transmitted from the central control unit.

Further, the dimming control system according to the third aspect has the effect of the first or second aspect, and furthermore, the dimming control terminal displays the dimming control intermediate state. Even when dimming control is performed for a long dimming fade time, it can be easily recognized that dimming is in progress.

Further, in the dimming control system according to the fourth aspect, the dimming level control based on a desired dimming fade time is performed by:
Since it is started simultaneously with the fade time information and the broadcast control signal sent after the dimming level information is sent, the central control unit operates by reducing the amount of data sent. The response time to is shorter.

Further, in the dimming control system according to the fifth aspect, in addition to the effect of the fourth aspect, the dimming level control based on a desired dimming fade time is transmitted after the identification data is transmitted. Since it is started simultaneously with the fade time information and the broadcast control signal, the effect of achieving a good dimming scene effect with less data amount transmission and less dimming control terminal storage capacity is achieved. To play.

According to a sixth aspect of the present invention, in addition to the effects of the fourth or fifth aspect, the dimming display terminal receives the broadcast control signal and the dimming fade time information to control the dimming. Since the status of control is displayed during control,
